Abstract

A torque transmission device includes an inner ring, an outer ring, and at least one pair of receiving bellows. The at least one pair of receiving bellows includes a positive receiving bellows and a negative receiving bellows. The torque transmission device also includes at least one gas pressure spring and an adjusting unit connected to the at least one gas pressure spring. The receiving bellows are arranged between the outer ring and the inner ring such that when the inner ring is rotated in the positive rotational direction, the positive receiving bellows may be compressed, and when the inner ring is rotated in the negative rotational direction, the negative receiving bellows may be compressed. In addition, the receiving bellows are connected to the at least one gas pressure spring in a fluidically conductive manner.
