A brake booster coupling device is described having a braking piston, an input piston, which is displaceable in the event of an operation of a brake input element from its starting position by a driver braking distance, a force transmission between the input piston, which is displaced by a driver braking distance below a predefined threshold value, and the braking piston is suppressed, and a booster piston, which is displaceable with the aid of the brake booster drive in such a way that the braking piston, which contacts the booster piston, is displaceable with the aid of the brake booster drive from a non-braking position into at least one braking position, the brake booster coupling device including a contact element, which is displaceable and/or deformable in the event of a displacement of the braking piston from the non-braking position into the at least one braking position in such a way that a first contact surface of the contact element contacts a second contact surface of the input piston, which is displaced by a driver braking distance from the threshold value, in such a way that a driver brake force is transmittable via the contact element to the braking piston.
