An assembly for an aircraft propulsion system includes a planetary gear assembly, a torque sensor, and a controller. The planetary gear assembly includes a sun gear, a plurality of planet gears, a first ring gear, and a second ring gear. Each planet gear of the plurality of planet gears includes a main gear, a first lateral gear, and a second lateral gear. The main gear is engaged with the sun gear, the first lateral gear is engaged with the first ring gear, and the second lateral gear is engaged with the second ring gear. The torque sensor assembly contacts the second ring gear. The torque sensor assembly is configured to generate an output signal corresponding to an axial deflection of the second ring gear. The controller is configured to calculate a torque applied to the output shaft by the planetary gear assembly using the output signal.
