A generator drive disconnect device comprises a drive transfer means 116 having a connected configuration and a disconnected configuration. The drive transfer means 116 transfers a rotational drive between an input shaft 120 and a rotor 110. The disconnect device further comprises a disconnect actuating member 140 moveable between an activated position and a de-activated position, and a moveable disconnect member 101 rotatable about a rotor axis of the generator. The disconnect actuating member comprises a rolling element bearing 141 and the moveable disconnect member comprises a ramp member 130, configured such that movement of the disconnect actuating member to its activated position causes the disconnect actuating member to engage the ramp member via the rolling element bearing, to axially displace the moveable disconnect member, to move the drive transfer means toward the disconnected configuration. Other aspects of the invention relate to an aircraft engine assembly and an aircraft comprising the generator drive disconnect device.
