The rigid central portion, the opposed end portions, and the flexible portions define a variable cross section torsion bar with the flexible portions comprising reduced cross-sectional portions of the torsion bar relative to the rigid central portion and opposed end portions. Armature assemblies and torque motor valve actuators are also provided.
