1. An air valve assembly for a gas turbine engine comprising:
a first valving element;
a second valving element rotatable about a first axis relative to the first valving element to control a flow of air through the first and second valving elements;
an actuator;
a linkage coupling the actuator to the second valving element to rotate the second valving element between first and second orientations; and
a plurality of follower member assemblies, each comprising:
an insertion portion extending through a corresponding first aperture in the first valving element and a corresponding second aperture in the second element, the insertion portion being circumferentially fixed relative to one of the first and second valving elements and circumferentially moveable relative to the other of the first and second valving elements.
