Abstract: A valve/actuator torque overload protector is disclosed as operably associated relative to driving and driven members which are pre-set to transmit limited torque during relative rotary movement between the members. A plurality of spring-loaded tapered rollers are mounted on one of the members for driving engagement with complementary detents on the other of the members. The spring-loaded tapered rollers are pre-set relative to the complementary detents*** in order to permit limited torque engagement of the driving and driven members during relative rotation thereof. However, upon encountering torque exceeding pre-set limits, the spring-loaded tapered rollers disengage from the complementary detent*** to interrupt the transmission of torque between the driving and driven members.
