              Callers can use the alias to refer to the instrument or hardware source.
              The alias should be lowercase, no spaces. The display name may be used to display alias to
              the user. Neither the original instrument or hardware source id and the alias id should ever
              be visible to end users.

              :param str alias_instrument_id: the alias of the hardware source id (lowercase, no spaces)
              :param str display_name: the display name for the alias
