An aircraft wheel drive arrangement 10 is provided with a torque coupling clutch assembly 40 that transfers torque to the drive system 38 actuating a non-engine drive means 36 to drive an aircraft landing gear wheel and move the aircraft autonomously in a desired ground direction and at a desired ground speed. The wheel drive system and clutch assembly are mounted completely within the wheel 12 where the clutch assembly is selectively engaged to control torque transmission to the drive system, which selectively transfers actuating torque to the non-engine drive means. A selectable one way clutch is adapted to controllably transfer torque to the wheel drive system and has selective engagement capability in a forward or reverse rotational direction so that torque required to move the aircraft is transferred only when required by aircraft operating conditions. The drive system may be a roller traction system and the clutch can comprise overrun and failsafe mechanisms.
