Abstract
A torque transmission mechanism includes a drive shaft () and a driven shaft (). The drive shaft rotates about an axis. The driven shaft extends along substantially the same axis as the drive shaft. A torque accumulator () serves to accumulate a rotational torque of the drive shaft and to transmit the rotational torque to the driven shaft due to a frictional force. A controller () serves to control the accumulation of the torque in the accumulator.
