Abstract: Provided is a brake device for braking a rotational movement of a shaft about the longitudinal axis, wherein the shaft is mounted so as to be rotatable about the longitudinal axis in a direction of rotation and in a counter direction which opposes the direction of rotation.

A brake device equipped with a setting device for mutually opposing setting of a braking torque on the shaft during rotation of the shaft in the direction of rotation, and a counter braking torque during rotation of the shaft in the counter direction is provided. Also provided is a method for controlling a brake device.
