Abstract : An actuator, which directly converts fluid pressure to rotary movement, has a generally cylindrical and helically fluted circumferential wall, an end wall bearing an output member, and a fixed opposite end wall. The actuator may be a one-shot device providing substantial torque and driving the output member through a relatively wide angle by having a pyrotechnic gas generating charge mounted inwardly of the fixed end wall and by exceeding the elastic limit of the circumferential wall which is metallic to so as to withstand pyrotechnically generated gas.
