Another Flexible Coupler

This is my attempt at a flexible coupler for joining the 5mm shaft of a stepper to a 3/8 inch leadscrew. It uses 6-32 screws for clamping. The two parts were joined with sugru. Alternatives would include oogoo, flexible hot glue, flexible epoxy or similar. Silicone caulking might work but would require a very long time to cure.
