An actuator assembly comprises a first diaphragm ( 422 ) and a second diaphragm ( 424 ) connected to the first diaphragm for forming a chamber ( 426 ) between the first diaphragm and the second diaphragm. An actuator shaft ( 427 ) is connected to first diaphragm ( 422 ) and is oriented to extend through the chamber ( 426 ) and to extend through an aperture formed in the second diaphragm ( 424 ). The second diaphragm ( 424 ) can be connected to an actuator body ( 450 ) wherein the actuator shaft ( 427 ) performs an actuation operation. Alternatively, one or more actuator amplification assemblies ( 400 (B)) can be interposed between the second diaphragm and the actuator body.
