A pair of flywheels 10, 20 drive a belt transmission system via respective flywheel pulleys 11, 21 and an output pulley 30. At least a major proportion of the belt pressure forces (Fs, Fd figures 3 & 5) applied by the tensioned belt 40 towards the output axis Xi of the at least one output pulley 30 act in mutual opposition. The flywheel pulleys may he arranged in diametrically opposed relation on opposite sides of the output pulley axis so that the torque transmission capacity of the belt transmission is not limited by the side loading limit (L fig. 1) of the output pulley bearings. The belt transmission may provide a continuously variable ratio and may be arranged for example to improve the acceleration of a prime mover 60 under load, or in conjunction with a continuously variable primary transmission to maintain output shaft speed while the prime mover 60 accelerates to match the increasing power demand of the load 90.
