Abstract
A method of actuating a clutch in a power transmission device having a first rotary member and a second rotary member includes compressing a spring, releasing the spring to pressurize a fluid, supplying the pressurized fluid to a piston, and applying a force from the piston to the clutch to transfer torque between the first and second rotary members.
