Abstract: A disconnect assembly comprises an angularly movable input member 24 arranged to be driven for movement by an actuator, an angularly moveable output member 32, and a drive member 36 connected to one of the input member 24 and the output member 32 for angular movement therewith and having a formation 40 cooperable with the other of the input member 24 and the output member 32, wherein the drive member 36 is axially movable between a drive position in which the formation 40 cooperates with the said other of the input member 24 and the output member 32 to transmit torque between the input member 24 and the output member 32, and a disconnect position in which the formation 40 does not cooperate with the said other of the input member 24 and the output member 32.

Abstract: A geared rotary actuator including first and second adjacent, axially aligned actuator slices, each slice having an epicyclic-type reduction gear train including a rotatable input sun gear, a planetary gear assembly driven by the sun gear, and first and second output ring gears driven by the planetary gears, the second output ring gear of each slice being an earth ring gear in use, and the two adjacent earth ring gears being interconnected by axially extending clip means limiting the amount by which said adjacent earth ring gears can be displaced from one another in an axial direction while permitting limited tilting movement of one of the earth ring gears relative to the other to accommodate flexure of the actuator about its longitudinal axis in use.
