Here's a top view of a SIG LT-40 which has a single aileron servo. The servo is mounted where the wing's root ribs meet, in a box. Each of the ailerons have a torque rod that transfers servo movement to the control surface. When the servo arm rotates, one servo arm attachment point moves forward while the other servo arm attachment points moves backward an identical amount. As a result one torque rod is pulled while the other is being pushed. The effect is that one aileron is rotated up and the other is rotated down.
