Couplings

An engageable and releasable rotary coupling for the non-relatively rotatable interconnection of two rotary machine parts the coupling comprising two coupling halves, one said coupling half including a screw-threaded member having an external taper thread, the other of said coupling half including a sleeve having a complementary internal taper thread screwably receiving the external taper thread of said one half to act as a coupling means for transmitting torque from one machine part to the other, the screw-threaded member and the screw-threaded sleeve being axially movable towards and away from one another, means associated with one of said machine parts axially moving one of said coupling halves generally axially relatively to the other thereby enabling a drive for one of the two machine parts and a brake device for the other machine part to be used in conjunction for engaging and releasing the coupling and wherein one of the screw-threaded member and the screw-threaded sleeve is axially slidably but non-relatively rotatably received with clearance on its respective rotary machine part and is provided with slots which extend substantially axially, whereby tightening of the taper thread eliminates said clearance.
