1. A switchable coupling device for a drive train of a motor vehicle, comprising:
a coupling having an non-torque-transmitting open position and a torque-transmitting closed position, and
an actuating device configured to be selectively moved between a base position and a switch position so as to adjust the coupling from the non-torque-transmitting open position to the torque-transmitting closed position, the actuating device comprising:
a first actuator element configured for moving the actuating device in a first switching direction,
a second actuator element configured for moving the actuating device in a second switching direction, and the second actuator element and the first actuator element are separate components,
a spring device, and in a pretensioned state, the spring device presses at least one of the first actuator element directly against a motor-adjustable switching contour in the first switching direction or the second actuator element directly against a motor-adjustable switching contour in the second switching direction, and
the actuating device has an intermediate position located between the base position and the switch position, and the actuating device is configured such that the actuating device in the intermediate position is pretensioned in a direction of at least one of the switch position or the base position.
