So, the lesson there is don't use aluminum shaft if you go that route!
Update for this...

We swapped out our prior solution tonight for the ½” socket bit option in the screen steps live link. it worked perfectly for our application. We don't really need the max torque the motor can put out, but rather the form factor and speed are what makes it a good fit for this particular application. Being able to get this working tonight after having our milled square solution break on Tuesday was really great - it's nice not having to wait for additional parts (if we were to go with the 3/8" hex option, as we don't have any of that in stock, only 1/2") or switch to a different solution. Having these options presented like this really made it easy to understand and made my student's evening!
