  thousand  eleven,  no  changes  in rates, rating plans, rating rules and
  rate manuals applicable to motor vehicle insurance,  including  no-fault
  coverages  under  article  fifty-one  of  this  chapter,  shall  be made
  effective until approved  by  the  superintendent,  notwithstanding  any
  inconsistent provisions of this article; provided, however, that changes
