If teams can't machine Dr Joe's drill output shaft because of various reasons, then the drill motor coupling is the way to go. The reason you shear the pins on the coupling is because there are too much load on the drill motor output shaft. One way to fix this is have another gear stage or sprocket stage, so that the second stage's shaft is taking the load instead, there the drill motor won't be taking as much load.
A lot of teams last year didn't have problems with these because they were light robots that didn't need to push a whole lot of stuff.
