#	Part	Qty	What it does
1	Coupling Shaft	1×	Steel rod (0.5 inch diameter), connects left and right solenoid bolts via rigid linkage
2	Coupling Collar	2×	Steel sleeves or flanges clamp solenoid plungers to coupling shaft, ensure synchronized motion
3	Return Spring Main	1×	Heavy compression spring (300 lbf) ensures coupling and bolts retract fully when de-energized
4	Fastener Set	1×	Set screws and locking pins prevent collar rotation or axial slip on shaft
