A right R-module M is called a QTAG-module if any finitely generated submodule of any homomorphic image of M is a direct sum of uniserial modules. Some results known from Abelian group theory concerning \(\sigma\)-purity, isotype subgroups and centers of \(\sigma\)-purity are extended to QTAG-modules.
