In order to form a torque transmission coupling to be compact, the present invention provides a torque transmission coupling ( 1 ) comprising input-output rotary members ( 57, 59 ) rotatably supported to perform input-output transmission of torque; a frictional engagement section ( 79 ) provided between the input-output rotary members to perform torque transmission between the input-output rotary members by enforcing frictional engagement; a compression member set ( 87 ) that comprises a pair of members ( 89, 91 )capable of performing relative rotation and that generates thrust through the relative rotation between the members to thereby cause the frictional engagement section to perform the frictional engagement; and a rotary actuator ( 121 ) that causes both of the members of the compression member set to perform engagement-rotational driving whereby to cause the relative rotation.
