The publisher typically has the exclusive right to grant the permission whether copyright is owned by the publisher or not. If the rightsholder requires that the credit line be in a specific format, this must be followed exactly as indicated by them. Example:

"Reprinted from Publication title, Vol /edition number, Author(s), Title of article / title of chapter, Pages No., Copyright (Year), with permission from Elsevier [OR APPLICABLE SOCIETY COPYRIGHT OWNER]."
