ophyd name kwarg values should be valid python object names #67
Description
The name="VALUE" kwarg should be a valid Python name.
Names such as these should be changed: https://github.com/aps-8id-dys/bluesky/blob/7ccd08c563eabc008954e55a2de48c468d7ff52a/src/instrument/devices/slit.py#L43-L47
While this is a naming convention that is not checked by the ophyd code, the names are used later to retrieve and reference data from the databroker or tiled. Names which are not suitable as Python object names are problematic to the end users.
This regular expression (derived from NeXus) is a good test for names: ^[a-zA-Z_]([a-zA-Z0-9_]*)?$
It has been recommended that the name match the Python object name unless a compelling reason suggestion otherwise.
