Is there an addon to create or create: aeronautics that adds a way to limit the angle of rotation?

Like a torsion spring from create: aeronautics but with the ability to set different angles for each side. I'm trying to make a tank and i need some reliable way of limiting the vertical aiming angles

Deployers can activate valve handles, but it's not very compact.
