Claim 0:
1. An electromechanical actuator assembly, comprising:
an actuator having an actuator shaft;
a servo shaft coupled to the actuator shaft, the servo shaft having a first end, the first end of the servo shaft having an opening extending into the servo shaft, such that the servo shaft has a sidewall extending around and defining the opening, the sidewall of the servo shaft is at least partially constructed of a ductile material, the servo shaft having a first hardness, a first modulus of elasticity, and a first fracture toughness;
a housing having an opening aligned with the first end of the servo shaft; and
a poppet positioned within the opening of the servo shaft and extending into the first end of the servo shaft, the poppet having a first end outside of the opening of the servo shaft, a second end within the opening of the servo shaft, and an outer surface extending between the first end of the poppet and the second end of the poppet, the poppet having a recess formed in the outer surface and positioned between the first end of the poppet and the second end of the poppet, the recess being defined by at least one sidewall and a bottom, at least a portion of the ductile material of the sidewall of the servo shaft being positioned within the recess of the poppet to secure the poppet into the opening of the servo shaft such that the poppet does not move relative to the servo shaft, the poppet having a second hardness greater than the first hardness, a second modulus of elasticity greater than the first modulus of elasticity, and a second fracture toughness less than the first fracture toughness.
