Unclear Annotation in Documentation Example

[dan-fernandes]

In the Readable section of the Make a Simple Device how-to guide, the type annotation in the example code reference A:

class Sensor(StandardReadable, EpicsDevice):
    """A demo sensor that produces a scalar value based on X and Y Movers"""

    value: A[SignalR[float], PvSuffix("Value"), Format.HINTED_SIGNAL]
    mode: A[SignalRW[EnergyMode], PvSuffix("Mode"), Format.CONFIG_SIGNAL]

I am not sure it is clear that A refers to typing.Annotated, as the import alias is not shown.

Acceptance Criteria:

• The documentation should be readable by a programmer unfamiliar with the codebase.
