Aerostructure actuator systems include first and second shaft portions (302, 304) having respective first and second mandrels (308, 310) and a clutch assembly (306) arranged within the first mandrel (308) and connecting the shaft portions (302, 304). The clutch assembly (306) includes a post (312) with a post extension (412) fixedly connected to the second mandrel (310). A first bearing (314) is installed on the post extension to frictionally engage with a portion of the post. A second bearing (318) is installed on the post. A spacer (316) is arranged between the bearings and is fixedly attach to the first mandrel. A load setting nut (322) is configured to engage with the post extension and apply a compressive force to the bearings and spacer against the post. The compressive force defines a coupling limit between the shaft portions. The clutch assembly (306) is configured to rotationally decouple the shaft portions from each other if a relative rotational speed between the shaft portions exceeds the coupling limit.
