### Expected behavior
Using `qml.transforms.classical_jacobian` by passing `argnum=None` with Torch interface computes the classical jacobian wrt. the trainable parameters.
```python
import pennyla…

### Expected behavior
When calling a simple circuit:
```
import pennylane as qml
dev = qml.device("default.qubit", wires=2)
@qml.qnode(dev)
def circuit():
qml.Identity(wires=0)
…

### Expected behavior
The `default.qubit.jax` device works well even when using the parameter-shfit rule.
### Actual behavior
For the tape interface, computing the jacobian of the tape provid…

**Describe the bug**
When using a rotate gate (such as RZ), if by mistake the user swaps the order of the parameters, no error flag is risen. This is a potential issue because in QISKIT, the order of…

When a task fails a user would like to know the information in failureResult. However, this is not easy to find and should be returned automatically when a task fails.

### Expected behavior
A jitted function can be defined multiple times. E.g., running the following in a Jupyter cell multiple times works:
```python
import jax
import pennylane as qml
@jax.ji…

### Expected behavior
Pickling and unpickling a qml.numpy.tensor object should result in an identical object. The unpickling does return a qml.numpy.tensor object, with the numerical values of the ar…

#### Issue description
In the [noisy circuits demo](https://pennylane.ai/qml/demos/tutorial_noisy_circuits.html), I get an unexpected error in the last cell when replacing the device with
`dev = …
