I appreciate all the ideas for help, but we had a veteran 3M engineer, a machinist, myself and 6 kids all scratching our heads on a fix for this. The motor output shaft of the motor on the linear actuator is all worm gear. It doesn't have an attachment to the shaft. It has a diameter similar to the shaft of the CIM motor. I can post pictures tomorrow if anyone wants to take a look at it, but I don't see an easy fix here.

Thanks for all the help and advice.
