Abstract
There is described an actuator device comprising a single molded housing, a linear bridge feature, a spring hook retention feature, and a power spring. The single molded housing is formed by integrating the linear bridge feature across the single molded housing and the spring hook retention feature to one side of the linear bridge feature. The power spring is inserted laterally through the linear bridge feature of the actuator device. The power spring includes a spring hook at one end, and the spring hook of the power spring attaches to the spring hook retention feature of the actuator device. The power spring applies, at least in part, a torque to a control shaft coupled to the actuator device.

An actuator device comprising:
- a single molded housing;
- a linear bridge feature integrated across the single molded housing;
- a spring hook retention feature integrated to one side of the linear bridge feature;
- and
- a power spring inserted laterally through the linear bridge feature of the actuator device, the power spring including a spring hook at one end, the spring hook of the power spring attaching to the spring hook retention feature of the actuator device,
- wherein the power spring applies, at least in part, a torque to a control shaft coupled to the actuator device.
A method for assembling an actuator device, the method comprising:
- forming a single molded housing for the actuator device, the actuator device including a linear bridge feature integrated across the single molded housing and a spring hook retention feature integrated to one side of the linear bridge feature;
- inserting a power spring laterally through the linear bridge feature of the actuator device, the power spring including a spring hook at one end;
- attaching the spring hook of the power spring to the spring hook retention feature of the actuator device;
- and
- applying a torque to a control shaft coupled to the actuator device, the torque being applied at least in part by the power spring.
