1. A method for making an apparatus, the method comprising:
- forming an actuator device with at least one actuator having components that move rotationally relative to each other about a pivot axis extending between opposing ones of the components, a platform rotatably coupled to the at least one actuator and a plurality of radially extending tabs disposed around an outer periphery thereof;
disposing an optical element on or in a central opening of the platform;
providing an annular structure having a front surface with plurality of slots disposed around a central opening therein, each slot having sidewalls complementary in configuration to corresponding sidewalls of a corresponding one of the tabs; and
inserting respective ones of the tabs into corresponding ones of the slots such that an optical axis of the optical element is disposed coaxially with a central axis of the central opening of the annular structure.

Abstract
A method for aligning an actuator device relative to an adjacent component, such as a rear cover of an actuator module or a stationary lens, includes disposing a plurality of radially extending tabs around an outer periphery of the actuator device, disposing a corresponding plurality of pairs of raised mounting features on a front surface of the adjacent component, each pair defining a slot having sidewalls that are complementary in configuration to respective sidewalls of corresponding ones of the tabs, and inserting respective ones of the tabs into corresponding ones of the slots.
