Tractor Ice Cream Maker

So I've seen several engine powered ice cream makers that use this stainless steel coupling.  It makes an easy removable connection between the driver shaft and the ice cream maker top gear frame.
In the add they call it a "Love Joy style" but its really different than a Love Joy since it has no rubber  spacer between the to coupling parts.  Seem like I've seen this somewhere else on some slow speed mixer machines.  
any help is appreciated to keep slowly identifying and gathering parts for my ice cream maker build.

Thanks for your assistance!

So, on a rainy day, i was browsing local craigslist on other ads.  I stumbled across a good amount of hit n miss engines for sale.  I found a few Maytag 92 motors relatively close for sale.  Well, after talking to a member on here, Im hooked.  Im in the process of looking for the right one.  Im gathering parts to make a wagon mounted ice cream maker.
