Abstract: A coupling device may include a coupler frame a variable length actuator having a right actuator end and a left actuator end supported by the coupler frame and extending between the ends of the coupler frame. Right and left latches are slidably engaged by and movable relative to the coupler frame and are operatively connected to the ends of the variable length actuator. The variable length actuator operates to move between retracted and extended positions and may be slidably mounted on the coupler frame so that ends move horizontally relative to the coupler frame and the variable length actuator does not move vertically relative to the coupler frame. The latches move relative to the coupler frame between unlocked and locked positions as the variable length actuator moves between the actuator retracted and extended positions, respectively.
