A coupling is provided for releasably joining two abutting sections of a drive shaft such as used to drive an inboard power boat. An inner sleeve within the coupling is replaceable and permits one shaft to rotate relative to the other within the coupling if a predetermined torque setting is exceeded without damaging the coupling. The torque "breakaway" point for the coupling can be adjusted by tightening or loosening the bolts connecting the two halves of the coupling around the shafts.
