The local analytic classification of irregular linear q-difference equations Ramis-Sauloy-Zhang involves the classfication of filtered q-difference modules with a prescribed associated graded module. We prove in a more general setting the existence for this problem of a moduli scheme which is an affine space. - La classification analytique locale des equations aux q-differences irregulieres se ramene a la classification de modules aux q-differences filtres a gradue fixe. Nous degageons ici des hypotheses generales qui assurent lexistence dun schema de modules pour ce probleme, qui soit de plus un espace affine.
