The outer member (36) defines an annular continuous frustoconical inner surface (46). A rotor disc (50) includes an annular protuberance (60) having an annular continuous frustoconical outer surface (64) complementary to the inner surface (46) of the outer member (36) and in torque-transmitting engagement therewith. The assembly includes means (70) for axially pressing the sleeve (30) and the disc (50) against one another to maintain the complementary frustoconical surfaces in torque-transmitting engagement. Corresponding method of engaging a rotor disc (50) to a driving shaft (20) in a gas turbine engine (10).",
