An elastic clutch is arranged as elastic non-metal tube cut along in screw line with formation of a cylindrical spiral element direction of turns of which is opposite to the direction of rotation of the drive shaft. At that in the inner section of the elastic non-metal tube cut along in screw line with formation of a cylindrical spiral element between the drive and driven shafts a ball is installed to spherical holes provided in the ends of the shafts, with diameter equal to the diameter of the larger shaft, in such way that the ball is in permanent contact with the spherical depressions, and the radii of spherical depressions are equal to the radius of the ball.
An apparatus comprises: a roller tube, a motor that includes a motor drive shaft and a motor housing, the motor housing for rotating with the roller tube, and a manual control that includes a manual control drive shaft coupled to the motor drive shaft, the torque application motor and for the roller tube through the rotation of the motor housing.
