A generator drive disconnect device 100 comprises a drive transfer means 116 having a connected configuration and a disconnected configuration, and a disconnect mechanism, configured to move the drive transfer means toward the disconnected configuration. The disconnect mechanism comprises an activation mechanism comprising a disconnect support member comprising a bore 142, and a disconnect actuating member 140, supported within the bore and arranged to move relative to the bore to actuate the drive transfer means to its disconnected configuration. An interface between the bore and the disconnect actuating member comprises a friction reducing arrangement, such as a linear bearing 146. The friction reducing arrangement may comprise a self-lubricating material such as an alloy impregnated with a lubricant, e.g. graphite, PTFE, oil etc. Other aspects of the invention relate to a generator, an aircraft engine assembly and an aircraft comprising the generator drive disconnect device.
