Abstract:
Rotary actuator lever apparatus having an annular recess are described. An example rotary actuator lever includes a cylindrical body that has a first opening and a second opening axially aligned with the first opening, and sized larger than the first opening. The lever arm extends a predetermined distance from the body and has a first arm member spaced from a second arm member. Each of the first and second arm members includes an aperture to receive a fastener to operatively couple the lever to a stem of an actuator. The body includes an annular recess adjacent the first arm member of the lever arm to enable the first arm member to flex relative to the second arm member when the lever couples to the actuator stem.
