shaft couplers

Just wondering what teams have used this method for quick transmission swaps at comp. The team that I mentor had a huge transmission failure going into the elimination rounds, and I thought that this would have saved the day for them. I brought this up to the CAD team and they loved the idea and will be implementing it hopefully in an offseason project. I would really love any thoughts from teams that have used the set-up.

Thanks
