A propulsor assembly for a turbine engine includes a propulsor and a propulsor actuation system. The propulsor has a plurality of propulsor blades. Each of the plurality of propulsor blades is rotatable about a blade pitch axis. The propulsor actuation system includes an actuator for rotating the plurality of propulsor blades and a trunnion mechanism that includes a plurality of trunnion assemblies. Each of the plurality of trunnion assemblies is coupled to a respective one of the plurality of propulsor blades and includes an outer sleeve coupled to a blade spar of the respective propulsor blade, an inner sleeve coupled to the outer sleeve, and an actuation member that engages the inner sleeve. The actuation member is rotatably engageable by the actuator to rotate the respective propulsor blade about the blade pitch axis.
