This is one of the autopilot servos for the EFIS. On one occasion, I think on our way back from Sun ’n Fun, I was coming in to land for fuel and all of a sudden I had an elevator jam. It turned out to be a set screw that had backed its way out of the shaft on this thing and wedged itself between the arm and the hole. That was a bit of a scare!

I’m glad to see the back of these. They were totally useless, and somewhat overkill for this kind of aeroplane compared to the size of the Garmin units.
