shaft spinner

Just mount a drill to a board...then you can chuck up any pin needed for a driver.
You can buy just a simple jacobs chuck pretty cheap, and depending on the type of motor shaft you have, there are several ways to mount it. I think I have seen decent keyed chucks for $10-$15 at HF and Grizzly, or keyless for $50-$60. Most are either threaded, or a morse taper, but I have seen straight shank with a keyway as well.

Joe Picone sells a setup where you can mount your maintenance pins right to the motor shaft, if you want to go that way.

I have been looking to do the same thing. Check Mcmaster-Carr. They are pretty must the last stop for any part you'll ever need. www.mcmaster.com

It might be easiest to couple the motor to a drill chuck using a pulley arrangement. Chucks typically have a (female) Jacobs taper (JT). They mount on an arbor with a male JT (or threaded) on one side , and a Morse taper or straight shank on the other. Get a straight shank arbor and run the shank in a couple of bearings with a pulley on the shank in between the bearings. A matching pulley on the motor, a little belt / O ring, and spin away. As an additional benefit, you could adjust the speed somewhat using different sized pulleys.
I've never seen a drill chuck arbor with a hole/set-screw to slide/lock onto a shaft ... even in McMaster-Carr. I mean what ID would you bore the hole at ? It would cost more to make as it cannot be simply ground between centers, and it would have a limited market. I don't think they exist.

I've never seen one either, but anyone with access to a metal lathe could make an adapter rather easily. You could really even make an adapter with just a drill press!
I did something like this a long time ago, and while it wasn't the greatest thing in the world, it did get me through for a while. I took my motor to a machine shop along with the drill chuck and just had them turn it and thread it. Shouldn't cost a huge amount, I think I was charged like $15.

Find one here that fits your motor/chuck config. Don't need the washers but use the nut to 'lock' chuck to arbor

Yes, you can make one rather easily, but with all the cantilevering and tight machining it's pretty easy to get a wobble or two (especially if you tried to make it using only a drill press using drill bits). If the bore for either the motor shaft or the arbor shank is larger than a sliding fit (we're talking tolerances in the +- 0.0005" range here), by the time you get out to the working end it's wobble city ! Heaven forbid you get both bores a couple thou too big.
Dave, been there, done that, tossed the things in the ever-growing pile o' scrap ... of course this could just be a hack machinist problem
<edit> OK, another idea would be to run a straight-shanked arbor in a pair of bearings, and couple the end to the motor using an adaptor ... that would take care of the wobble problem too

Unique products has a drill chuck 1/2" round hole with a set screw setup like you are looking for. They use it on their taper machine. Don't know what the cost is but it may be just what you need.

Normally with a threaded drill chuck, you have to mount it on a threaded stud that's meant for a drill. It will have normal threads on the outside, and reverse threads for a small flat head screw on the inside. That way, it's locked in both directions.
If you're hellbent on mounting that threaded chuck to a motor shaft, you've got some modications to be done that it sounds like will be more trouble than you're thinking. This is what the Shaftmaster is like, I believe.
IMO, for direct drive on a shaft motor (tell us what kind of motor you're using), you can ... have an arbor made to mount on the shaft, and then glue a rubber cane tip on it. I actually tried this out, but the shaft didn't spin squarely so make sure you have a motor that's stout enough and spins nice and squarely (no runout).
A bunch of us have made the kind of spinner tool describe above with the cane/seat tip, but usually it's held in jaws of a chuck. Prototype Shaft Spinner

I looked at grainger's website and msc's website, they both carrry an adaptor that you can bolt a chuck on a motor shaft. they are around 5 bucks.
