Abstract
A decoupler is disclosed for transmitting a drive torque from a rotary drive to a rotary output. The decoupler may include a first spring collar arranged on a drive-part side of a first end of a coil torsion spring and a second spring collar arranged on an output-part side of a second end of the coil torsion spring. The spring collars include axially ascending ramps, and the ends of the coil torsion spring resting thereon widen the coil torsion spring radially with transmission of a drive torque. The ends of the coil torsion spring and the spring collars include reciprocal rotary stops that prevent a relative rotation of the second spring collar with respect to the second coil torsion spring end and of the first coil torsion spring end with respect to the first spring collar.
