1. A clutch for coupling and uncoupling a motor to and from a motor vehicle drive train, having a piston which is arranged in a housing between two pressure chambers so as to be axially displaceable due to pressure, wherein the piston is connected to an actuating cap which is arranged for contacting or moving a sliding sleeve, wherein an end stop disc which is designed to be elastic in the axial direction is provided in order to limit the axial displaceability of the sliding sleeve, and wherein the end stop disc has an S-shape or double S-shape in a longitudinal section along the axis of rotation of the clutch.
