A drive arrangement (10) for a shaft (12) has a module carried by the shaft (12) and including a motor (14), a driven wheel (16) and a drive wheel (36). The motor (14), gearbox (38) and drive wheel (36) are carried on a slider plate (42) which can slide transverse to the axis of the shaft (12). A front plate (28) is fixed transverse to the axis of the shaft (12). A Bowden cable (50) has its sheath (51A) attached at (52A) to the front plate (28), and its inner cable (51B) attached at (52B) to the slider plate (42), so that manipulation of the Bowden cable at a remote location allows force to be applied between the plates (28, 42), either tightening the belt (34) to apply drive from the motor (14) to the shaft (12), or releasing tension the belt (34), to disengage the drive. |
