There are two actuator rod drivers per control stage (one for each actuator rod.
The actuator rod drivers propel the off-normal actuator rods, during phase 4 of operation.
The picture shows one actuator rod assembly and the components of the linkage which connect the pair of actuator rods of a control stage together. The linkage is composed of the white (arity 8) connector with the two blue struts attatched and two of the white struts with gray (arity 1) connector and pink clip.
Pictured below are two actuator drivers installed on the control frame. The red struts on which the actuator drivers are hinged mount on the control frame. The pair of actuator rods are connected by the linkage which is suspended from the gray strut of the control frame so that it can slide from front to back, moving the actuator rod drivers as it does.
