A rotary travel limit stop apparatus having a first rotary member (10) and second and third independently rotatable members (14 and 20) having slightly different numbers of gear teeth which engage the gear teeth on a first member (10) carry a movable stop pin (30) which is adapted to engage a fixed stop member (40) only during a revolution near the limit stop position of a controlled element such as an aileron. A stop plate (54) carrying a fixed stop member (40) is angularly adjusted by rotation of a screw (70) which is received by a barrel nut (64) that is coupled to the stop plate (54) by a protuberance (66).
