That would be called the throttle drum or throttle lever.

These cruise controls are a pain to diagnois. I've seen a few that just
like yours; everything checks out, but it don't work. :-/
Two things I have found. Either the ascd contol unit (rare), or the pump
is not pulling hard enough to actually move the actuator (even though it
works when you test it).  If you have access to a hand vacuum pump,
apply vacuum to the actuator and see if it holds. If that's OK, then you
probably have a bad valve in the pump. Electrically it works, but they
leak.
If you know for sure that's OK, then it has to be the ASCD control unit. :(

One more thing; are you sure the speed sensor works properly? If it's
not 100% the cruise will not set (but the light shouldn't stay on
either) but I've seen stanger things.....

PS: I'm on digest.....
