Team 330, beachbots have used that motor for the killer ramp they had. Take a look at their machine.

If I was to use the couplar, I would take few things into consideration. For example, what am I using it for, are there going to be a lot of torque involved for doing the job, is the plastic couplar good enough, or should I make a couplar out of aluminum, is it going to survive throughout the season. I would modify/add things to the couplar itself to make it work for what I want it to do.
