A disconnection coupling (11) is provided for installation between the input shaft (41) of an accessory and an engine to which the accessory is mounted. An input member (20) of the coupling (11) is connected to the engine in lieu of the accessory's input shaft (41). This provides engine power to the input member which can be selectively transferred to the accessory's input shaft. An intermediate member (30) is rotationally connected to an output member (40) which, in turn, receives the accessory's input shaft (41). The intermediate member (30) is able to be axially displaced with respect to the output member (40), while a spline joint (35) maintains the rotational connection between the intermediate and output members (30, 40). A release ring (47) and a braking spring (55) cooperate to cause a sleeve (57) to apply braking force and to axially displace the intermediate member (30) in order to disconnect the curvic coupling (29) and consequently disengage the accessory's input shaft (41) from the input member (20). When the release ring (47) is moved to a position to allow connection of the curvic coupling (29), a solenoid (69) normally latches the release ring (47) in that position.
