1. A fluid transmission system adapted to provide a controlled force to a dynamic system, comprising:
- a controller;
drive system coupled to receive a plurality of force feedback and/or motion feedback control values from the controller;
a first actuator coupled to the drive system;
an interface to the dynamic system;
a second actuator coupled to said interface; and
a fluid path coupled between the first and second actuator, said fluid path containing a captured volume of fluid for transmitting a force from the first actuator to the second actuator such that said second actuator provides a controlled force to the interface with the dynamic system; and
one or more impedance shapers disposed in said fluid path.
