Autopilot "pivot"???

My below deck simrad/robertson (350L drive unit) autopilot mechanism is loose and "pivots" on its base (around the shaft that connects to/controls the rudder post). It''s not a huge movement; maybe a 1/2" twist. I was wondering if anyone knows ... is the unit NOT tight enough? Or perhaps, is the pivot an intentional part of the mounting design, to allow some variation as the shaft moves from side to side (when you turn the wheel from stop to stop)???

I can''t find anything about it in the manual saying the "play" in the mounting is correct. I also can''t find an bolt, screw or other attachement that would tighten the unit more solidly to the base. This is why I''m not sure if it''s appropriate movement or not.

When you say shaft, are you refering to the pushrod shaft being able to twist? I''m not quite getting the picture. Can you describe further?

Yes, the "pushrod". When I grab the "drive unit" it moves slightly fore and aft (around the push rod; without disturbing the push rod) on it''s mounting. The mounted "base" is secure, but the unit that actually moves the push rod from side-to-side (thus rotating the rudder post) is not rock solid. It has some play. Once again, I can''t tell if this is by design or not. If someone else has the same unit, they may be able to tell me by simply seeing if their drive unit is "completely secured" to the base or does it have some fore/aft play (which kinda rotates around the push rod).
